DYEING-MACI-IINE.

Specification of Letters Patent.

Patented Oct. 10, 1916.

To all whom it may concern:

Be it known that I Fnnonnrc S. WILLIAMS, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Dyeing-Machines, ofwhich the following 1s a full, clear, and exact description. such as will enable others skilled in the art to whlch it appertains to make and use the same.

This invention relates to dyeing machines, washing machines, and the like, and with respect to its more specific features, to machines of the type employing rotatable yarn sticks.

One of the objects of the invention is the provision of a simple and eflicient tripping mechanism.

Another object of the invention 1s the provision of a practical tripping mechanlsm adapted to effectively cause rotation of the yarn sticks as the machine operates to dye materials and which also is of a character to avoid fracture of the machine parts in the event of substantial obstruction to the normal rotation of the yarn sticks.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application ofcwhich will be indicated in the following claims.

In the accompanying drawings, forming a part of this specification and wherein sl mlar reference characters refer to similar parts throughout the several views, Figure 1 is a perspective view of a portion of a dyeing machine embodying theinvention; and Fig. 2 illustrates one pos1t1on of the trip mechanism.

Referring now more specifically to the drawings, the numeral 1 indicates a caslng adapted to contain dye liquor, and 2 1nd1- cates a portion of a reel rotatably mounted so as to dip into the dye liquor. Supported by the reel are the yarn carriers comprlslng the yarn sticks 3 and 4, arranged in sets on the reel as usual. The outer sticks 3 are preferably square in cross-section and their square ends are received in square sockets.

111 a rotatable member 6, having arms 7 The members 6 are rotatably mounted on the reel, and are adapted to be rotated in onedirection by a trip hereinafter described, reverse rotation of said members being prevented by pawls 8, pivoted on the reel and engaging ratchet teeth 9, on the rotatable members 6. The reel may be rotated by any suitable means, preferably being coupled witha motor so as to be automatically rotated, and thereby translate in circular path the yarn carried on the sets of sticks, the yarn being thereby carried into and out of-the dye liquor as the reel rotates. Then the yarn is held in stationary position on the yarn sticks 3 and 4, these sticks in a measure prevent contact of the dye liquor with that portion of the yarn in contact with the stick, resulting in non-uniform dyeing. Hence in this class of dyeing machines it is desirable to move the yarn rela tive to the sticks so as to equally expose all portions thereof to intimate contact with the dye liquor. In order to effect this movement of the yarn, a trip 10 is provided, with which trip the arms 7 cooperate, being brought into contact with a projecting portion 11 thereof as they are translated by the reel. The trip 10, in the normal dyeing operation, depends in the translatory path of one or the other of the arms 7, and is designed to offer such resistance to the passage of said arms that the member 6 will be partially rotated by the trip in passing thereby. Should the yarn become entangled in any manner so as to obstruct or prevent rotation of the member 6 by said trip, or should the rotatable member 6 stick or be otherwise obstructed or prevented from rotating, there is a tendency to abnormally strain the mechanism, which frequently results in fracture of portions thereof, and especially of the arms 7. The main object of the present invention is to provide a practical trip mechanism which will offer sufficient resistance to the passage of the arms 7 to effect the partial rotation of the members 6, and which is capable of yielding under abnormal strain, so as to avoid the fracture of the mechanism.

In the present embodiment a horizontal rotatable shaft 12, is journaled in a bracket 13, fastened to a suitable part of the frame of the machine. The trip 10 is so connected to the shaft 12 as to rotate said shaft under certain conditions, and preferably this connection involves an eccentric pivoting of the trip relative to the axis of the shaft 12. This eccentric pivoting is accomplished by pivoting the trip at 14-, to a bifurcated arm 15 mounted to rotate with the shaft 12, said arm being embodied in a clevis removably fixed to one end of the shaft by a set-screw 16. Also connected to the shaft 12, so as to rotate therewith are abutment faces 17 and 18, transversely disposed relative to said shaft, and respectively on opposite sides of the line joining the pivotal axes of the shaft and the trip, these faces being opposite similar faces 19 and 20 on the trip. It may here be noted that the trip is comprised in an angle lever, the arm 21 of which extends substantially horizontally and serves to gravitatively urge the arm or trip 10 in a direction to cause the abutment face 19 to approach the face 17. The abutment faces 17 and 18 are preferably provided as a part of the clevis or arm 15, with which they may be cast.

A spring 22 is connected to the shaft 12 and to a normally stationary member, so as to restrain, or resist, rotary movement of the shaft 12 under the influence of the trip 10. Preferably this spring is coiled around the shaft 12, and is connected thereto through the instrumentality of a collar 23, which may be rotatively adjusted on said shaft and fixed to the shaft in any desired adjusted position by set-screw 24:. The normally stationary member to which the other end of the spring 22 is connected may be a part of the fixed frame of the machine, but is preferably comprised in a pin 25 on a manually movable member 26. Preferably this member 26 is a hand lever rotatably mounted on the shaft 12, and supported in normal operative position by a rest 27, against which the lever 26 lies so as to be held from accidental downward movement. The rest 27 is comprised in the bracket extension 28, and the lever 26 may be sprung laterally so as to escape the rest 27, whereupon it may swing to a lower position, pivoting around the shaft 12. Vhen the spring 22 is tensioned by rotary movement of the shaft 12, said spring reacts and tends to rotate the shaft 12 in the opposite direction, and rotation of said shaft in this opposite direction is limited by a stop which may be comprised in a fixed portion of the frame of the machine, but which preferably is comprised by a shoulder 29 on the hub of the adjustable hand lever 26, the shaft 12 being provided with a stop lug 30 adapted to cooperate with the shoulder 29 and to rest thereagainst.

The operation of the apparatus is as follows: As the reel rotates the arms 7 are translated relative to the trip and the arms 7 of the members 6, successively come into contact with the projection 11 of the trip. If there is no abnormal resistance to the rotation of the member 6 then to be partially rotated, the tension of the spring 22 will be sufficient to prevent substantial rotation of the shaft 12, and hence the member 6 will be rotated in the direction of the arrow a.

Each successive member 6 will be similarly partially rotated, and thus the yarn will be moved relatively to its supporting sticks. When the rotation of the members 6 is prevented for any reason, as explained, the trip abutment face 19 will be pressed against the shaft abutment face 17, and the trip and shaft 12 will rotate as one around the axis of this shaft, the spring 22 permitting this and being gradually increased in tension. Eventually the trip will be forced aside by the arm 7 against the restraint of the spring 22, whereupon the arm 7 may continue farther in its translatory path, and the trip will be restored to position in the path of the succeeding arm 7 under the influence of the spring 22, the shoulder 29 cooperating with the lug 30, to limit this reverse movement of said shaft.

Should it be desired to rotate the reel in the opposite direction to that hereinbefore referred to, it will be noted that the trip 10 may freely revolve on its pivotal axis 1st in the opposite direction, as indicated by arrow 5, its movement in this direction being limited by the face 20 contacting with the face 18. The weight of the arm 21, will restore the trip to operative position, after its reverse rotation, which operative position is preferably with the faces 17 and 19 in contact, though a slight preliminary movement would not matter. By springing the lever 26 over the edge of the rest 27, the trip may be thrown into inoperative position, the lever 26 then depending as shown in Fig. 2.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
